RAILROAD-TIE Specification of Letters Patent.

'Patented-Aug. 13, 1907.

Application filed December 20, 1906. Serial No. 348,762.

To all whom it may concern: I

Be it known that I, CALVIN ADAMS DAMRON, a citizen of the United States, residing at Covington, in the county of Alleghany and State of Virginia, have invented certain new and useful Improvements in Rail road-Ties; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to railroad ties, and has for its object to provide a device of this class to be employed in place of the usual wooden ties now in common use.

A further object of my invention is to provide a metal tie having blocks of wood or other suitable material to receive the spikes; said blocks being constructed and arranged in such manner that splitting thereof by the spikes is prevented and strength and rigidity assured.

With these objects in View my invention consists in the novel construction of the blocks, binding bands and straps, and also in certain combinations of parts, all of which will be first fully described and afterwards specifically pointed out in the appended claims.

Referring to the accompanying drawing: Figure 1 is a perspective view of the tie showing rails in position. Fig. 2 is a plan view of tie showing one rail in position. Fig. 3 is a perspective view of one of the blocks. Fig. 4 is a vertical transverse section taken on line 4-4 of Fig. 2. Fig. 5 is an elevation of combined binding band and strap. Fig. 6 is a plan view showing a slight modilication. Fig. 7 is a fragmentary view showing parts in the act of being assembled. Fig. 8 is a vertical longitudinal section taken through Fig. 6, and Fig. 9 is a perspective View of the lock.

Like numerals of reference indicate the same parts throughout the several figures, in which:

1 indicates the metal tie which as shown is constructed in the form of a channel and having the two vertical walls 2, each of said walls being provided near each end of the tie with preferably two tongues 3.

4 indicates the blocks upon which the rails rest, each of said blocks being provided with preferably four vertical grooves 5 registering with the tongues 3 on the tie. The extreme ends of the blocks are reduced at 6 to ac comniodate the metal binding bands 7, said bands being provided with a strap 8 on the tops thereof, the

ends of said strap being bent downwardly at 9 as shown in Fig. 5..

Referring to Fig. 6 which illustrates a slight modification it will be seen that one pair of tongues 3 are provided near each end of the metal tie 1. In this construction the block 4 is inserted in the tie and buts against the two tongues 3 and is held in position against vertical movement by the strap 8. When the block is in position shown in Figs. 6 and 8 the lock 3 is inserted at the outer end of the block 4, said lock fitting snugly between said block, and an upwardly projecting flange 12 on the bottom of the metal tie l. The lock 13 is provided with a flange 18 which enters the notch 20 in the end of the block 4, and said lock 13 comprises a base 14, sides 16, front wall 15 and perforations 17 in' the walls 16 in such manner. that bolts 19 may be passed through the sides of the metal tie 1 and through the sides 16 of the lock 13 in order to rigidly hold the said lock in position within the metal tie 1.

Having thus described the several parts of my invention its operation is as follows: The blocks being first banded with the bands 7 the same are inserted in the tie, the tongues 3 on the tie entering the grooves 5 in the blocks, thereby preventing any lateral movement or play of the blocks. The blocks being thus in position the downward extensions 9 of the straps 8 project down along the sides of the tie as shown in Fig. 4-, and by means of suitable stud bolts 10 passing through the straps 8 and into the tie the entire structure is rigidly bound and tied together. The rails are then placed in position and securely spiked to the blocks, that portion of the tie directly under the rails being cut away at 11 in order to insure the rails bearing on the blocks.

By this construction the combined band and strap strengthen the block in such manner that there is little or no liability to split, which the straps 8 tie the blocks and rails to the tie in such manner that the ties can be raised by jacking the rails.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent oi the United States is:

. l. The combination of a channel tie provided with one or more tongues on the inner side of the vertical walls of the channel tie, blocks of wood or suitable material provided with one or more vertical grooves constructed to be inserted in the said channel tie, the said tongues on said tie entering the said grooves in the blocks, substantially as described.

2. The combination of a channel tie provided with one or more tongues on the inner side of the vertical walls of the channel tie, blocks of wood or suitable material provided with one or more vertical grooves constructed to be inserted in the said channel tie, the said tongues on said tie entering the said grooves in the blocks, and a metal band encircling each of said blocks, a binding strap formed on each of said bands and having depending ends constructed to be secured to the walls of said tie, substantially as described.

3. The combination of a channel tie provided with one or more tongues on the inner side of the vertical walls of the channel tie, blocks of wood or suitable material provided with one or more vertical grooves and constructed to be inserted in the said channel tie, the said tongues on said tie entering the said grooves in the blocks, and a met strap associated be secured to the Walls of sai scribed.

4. The combination of a channel tie re tongues on the inner side of the vertical d or other suitable material he channel tie and tongues, and

or mo the channel tie, blocks of woo inserted between the vertical walls of t constructed to abut against said one or more al band encircling each of said blocks, and a binding with each of said bands and arranged to d tie, substantially as deprovided with one walls of In testimony whereof, I aflix my signature, in presence of two witnesses.
